Enteral feeding pump system

a pump system and enteral technology, applied in the field of enteral feeding systems, can solve the problems of increasing the overall cost of requiring a large number of compressions, and adding significant costs to the rotary peristaltic system, so as to reduce the overall cost of the enteral pumping system, reduce the overall cost, and reduce the cost of tubing

AI Technical Summary

Benefits of technology

The system achieves efficient unidirectional fluid delivery with reduced mechanical stress and lower costs by using low-grade PVC tubing, capable of delivering larger volumes per stroke with fewer compressions, thus enhancing the overall efficiency and affordability of enteral feeding.

Problems solved by technology

The tubing segment made of silicone rubber and associated hardware add significant costs to the rotary peristaltic systems.
The pumped volume per stroke for this approach is typically very small so that a relatively large number of compressions are required to meet flow demand and mechanical pumping components are stressed.

Embodiment Construction

[0039]In accordance with the invention of FIGS. 1-10, the invention generally relates to enteral feeding systems, and in particular enteral feeding pump systems. More specifically, the invention relates to an enteral feeding pump system for delivering medical fluids unidirectionally including a disposable fluid delivery set having a repeatable compression portion which is helically coiled to define a cylindrical shape. The compression portion pumps a large volume of medical fluids per stroke. Also, an enteral feeding pump configured to repeatedly and reliably compress the compression portion of the fluid delivery set along a central axis.

[0040]Referring to FIGS. 1-7, an enteral pump feeding system 60, 70 for delivering medical fluids unidirectionally includes a disposable or replaceable fluid delivery set 20, 30 having a repeatable compression portion 10 and an enteral feeding pump 40. The disposable fluid delivery set 20, 30 is configured for engaging with an enteral feeding pump 4...

Abstract

An enteral pump system for delivering medical fluids unidirectionally includes a disposable fluid delivery set having a repeatable compression portion and an enteral feeding pump. The repeatable compression portion is helically coiled around a central axis to define a cylindrical shape. The compression portion is configured to pump a large volume of medical fluids per stroke. The compressing portion includes at least two adjacent tubing walls joined around the central axis for repeatable compression. The enteral feeding pump is configured to repeatedly and reliably compress the compression portion of the fluid delivery set along the central axis. In operation, the compression portion is repeatably compressed without distortion along the central axis by the enteral feeding pump to flow unidirectionally through the fluid delivery set.

Description

CROSS REFERENCE TO RELATED APPLICATION[0001]This application is related to and claims priority from earlier filed provisional patent application Ser. No. 61 / 073,964 filed Jun. 19, 2008, the entire contents of which are incorporated herein by reference.BACKGROUND OF THE INVENTION[0002]The invention generally relates to enteral feeding systems, and in particular enteral feeding pump systems. More specifically, the invention relates to an enteral feeding pump system for delivering medical fluids unidirectionally including a disposable fluid delivery set having a repeatable compression portion which is helically coiled to define a cylindrical shape. The compression portion pumps a large volume of medical fluids per stroke. Also, an enteral feeding pump configured to repeatedly and reliably compress the compression portion of the fluid delivery set along a central axis.[0003]Enteral feeding pump systems are used to supply fluid nutrition to patients who are unable to eat. The pumping sys...
